Most people don't enable identd for good reason. But for IRC, it remains a de facto standard requirement if you want to take full advantage of the networks. How do you enable identd without making it annoying?

• Use port triggering to enable it only when you connect to an IRC daemon.
  
• Make sure that identd does allow username authentication, otherwise, ircd isn't going to use it at all.
  

If you restrict access to the identd daemon to only that first minute while you connect to IRC, you're minimizing exposure and getting the benefit as well.
